| 摘 要： | 针对重型车辆传动桥二次调节模拟加载试验台,分析了液压耦合和机械耦合对系统控制性能的影响。仿真研究结果表明,模拟驱动的转速控制子系统与模拟二桥和轮边负载的转矩控制子系统之间的机械耦合干扰误差较大,明显降低了系统的控制精度。通过在系统中加入特定的解耦控制元件,实现了二次调节模拟加载系统的解耦,使各子系统成了接近完全独立的控制系统,有效地消除了耦合的不利影响,使系统的控制性能得到了显著改善。所采用的解耦方法,为实现二次调节模拟加载试验台的解耦控制、进一步提高整个试验台的工作性能,提供了一种有效的途径。

| Abstract: | The influence of hydraulic and mechanical coupling
on control property is analyzed in the secondary regulation load
simulation test equipment for the drive axle of heavy vehicle.
Simulation shows that disturbance error caused by mechanical
coupling between the speed control subsystem to simulate the
drive and the torque control subsystem to simulate the loads on
the secondary axle and wheel edges are comparatively large and
may obviously decrease the control accuracy of the whole sys-
tem. Certain decoapling control elements can be installed to the
system so as to make each subsystem almost independent of
each other,realize decoupling of secondary regulation load
simulation system, eliminate deteriorating effect of coupling
and finally quite improve control property.The decoupling
strategy proposed provides an efficient way to realize decou-
pling control of the secondary regulation load simulation test
equipment and to enhance its performance. |
